- adds new `KoenigHtmlTextarea` component for entering multi line html in cards
- updates accordion card to use html text area component
no issue
- added the edit toolbar icon back to the email-cta card
- switched back to displaying the non-editable version of the card when not in edit mode
- removed unused `showSettingsPanel` property from `<KoenigCard>` component, cards can now control display of settings panel using `@isEditing`
- removed unused `@visible` argument for `<KoenigSettingsPanel>` component
no issue
UI experiment (behind the `cardSettingsPanel` labs flag) for pulling card settings out into a separate side-panel. Prototyping against the email-cta card.
- shows panel immediately when selected unless selected by keyboard in which case it will wait for mouse input
- panel position is fixed so it's always on screen
- initial position tries to be as close to centered right of the card as possible
- ensures all of the panel is on-screen, will overlap the card if there's no enough horizontal width
- re-positions after window resize
- card no longer has a separate edit mode, the text replacement field is directly editable
- added empty archive screen
- added indication of archive offer on detail page
- set default dropdown style to non-selected
- removed archive button for new offers
no issue
- CSS that was used to fix positioning of the dropdown menus on the labs theme list was too liberal. Fixed by adding a specific class for the theme list dropdowns
refs https://github.com/TryGhost/Team/issues/1111
Extracted functionality for listing, downloading, activating, and deleting from the theme controller/template into separate components and services so that they are more composable/reusable in different situations.
- moved theme activation to a new `theme-management` service that uses the `modals` service to open the theme warnings modal or limits upgrade modal as required
- the activate process is a task so that consumers can store a reference to the task instance and cancel it to close any related warning/limit modals (eg, when navigating away from the route or closing the modal that kicked off the process)
- created new-pattern modals for custom theme limit upgrade, theme errors, and delete confirmation so that we can treat them as promises and close where needed from parent
- duplicated theme table component as `<GhThemeTableLabs>` with an actions redesign and a refactor to handle download, activation, and deletion itself making use of the new theme-management service and modals
- fixed some oddities with design modal's transition/modal close handling by simplifying the async behaviour and being more explicit
- added advanced design modal that contains the new theme table component and linked to it from footer of design modal's sidebar
refs https://github.com/TryGhost/Team/issues/1111
refs https://github.com/TryGhost/Team/issues/1103
- moved customize modal from a link on the design screen to the main design screen
- changed modal design to be a full-screen overlay with side bar that emulates standard Admin design
- added toggled groups of settings in sidebar
- added `{{set-has}}` helper for use in conditionals matching when a Set contains an object
- added grouping of theme settings
- dropped unfinished advanced/change theme modals
refs https://github.com/TryGhost/Team/issues/559
We want to get rid of our existing modals implementation because it doesn't play well with Glimmer compoments and the animation library it uses is now unmaintained and blocking our Ember.js upgrades.
- installed addon using customised fork
- fork allows passthrough of `allowOutsideClick` to `focus-trap` so we can allow clicks on dropdowns and other wormholed content inside of a modal
- extended the `modals` service locally so we can customise click-outside-to-close behaviour and tie in with our `dropdowns` service
- set up styles in `modals-new.css`, mostly copied from `modals.css` with a few specific overrides
- once all modals are converted we can drop the old `modals.css` and rename `modals-new.css`
closes https://github.com/TryGhost/Team/issues/977
A new label input dropdown was added behind filtering labs flag along with new filtering UI on members list screen, which includes member editing directly via the dropdown. This adds the same editing function to the members detail screen too behind the flag
no issue

- fixed styling so there isn't double padding around grouped options

We use vertical-collection to allow infinite loading + scrolling for members list instead of loading and rendering all members at once. The behavior was not working correctly with updated list for filtering feature, as we dynamically update columns. This change fixes the scroll behavior and members loading together by updating the containerSelector for vertical collection.
refs https://github.com/TryGhost/Team/issues/993
- added calls to `onFocus()` and `onBlur()` arguments inside the trigger when the input is focused/blurred so that the active class is correctly applied by ember-power-select
- removed unnecessary mousedown propagation cancellation, it was a copied from `<GhTokenInput>` where extra mouse handling is necessary for buttons inside tokens
- updated `.gh-input-with-select` styles to add the border when active
no issue
- Koenig is making use of other Admin-provided components which meant that editor-specific styles for those components were increasingly needing to make use of `!important` to override those component styles (specific example is using power-select based components) due to the order that CSS was loaded
- Koenig styles don't really fit with the other generic utility classes inside spirit so it makes sense to elevate them to the same level as other component styles within Admin's CSS
refs https://github.com/TryGhost/Team/issues/987
- `<GhInputWithSelect>` acts as a typical text input element but will also show options that are filtered whilst typing. Useful for inputs where there should be suggestions or the ability to choose an existing option
- updated `<GhSearchInput>` to use the renamed and slightly modified trigger
refs https://github.com/TryGhost/Team/issues/971
We use vertical-collection to allow infinite loading + scrolling for members list instead of loading and rendering all members at once. Since the members list behind filtering flag had a child container with fixed height, the list was not automatically loaded on scroll.
refs https://github.com/TryGhost/Team/issues/966
With introduction of members filtering, the current way of editing member labels needed an upgrade. This change updates the member label input component to include editing option which allows triggering label edit modal directly from the filtering menu when working with labels. The long term idea is to make this a consistent global pattern with labels dropdown, extending to member details screen as well.
refs https://github.com/TryGhost/Team/issues/943
The filter UI behind labs in Admin allows filtering members list across several filters. Since each filter type can have its own specific set of values to choose from, this change adds custom UI based on filter type to select filter value.
refs https://github.com/TryGhost/Team/issues/927
- added CTA `button and url inputs to email-cta card
- added `textColorForBackgroundColor` color util and used it to add a white/black text color variable that can be used when the accent color is used as a background color
- added `{{hex-adjust}}` helper for modifying lightness and saturation of a hex color
- adjusted inline power-select dropdown styling
refs https://github.com/TryGhost/Team/issues/926
- updated `<KoenigEditor>` so it creates default card payloads as TrackedObject instances so that getters in glimmer component based cards can track changes to payload properties
- added dropdown free/paid selector to email-cta card that sets the `segment` payload property to the respective filter
- updated design to show the footer outside of edit mode too so that the selected segment is always visible
- added max height to theme uploader modal container to avoid long list of errors leaning out of screen
- added shadow on top of footer to indicate long list of errors
refs https://github.com/TryGhost/Team/issues/840
We wanted to switch to a settings menu that stays open to the right of the editor rather than a popover that blocks all other interaction with the post to solve two use-cases:
1. when editing it's fairly common to select some text from the post contents when setting excerpt and meta data text, with the previous design not letting you scroll or select whilst the menu got in the way of that
2. having the menu open with meta data visible before publishing can help you see everything is set as you want and help you feel confident when publishing/sending content

Free and Paid are by far the two most common options for email recipients so it makes more sense to have them as very clear options which we felt was not the case with the single token/segment select.

- updated draft and scheduled publish menu components to use the `<GhMembersRecipientSelect>`

The publish menu was meant to default to matching post visibility but that wasn't working consistently and didn't make sense for sites which don't email every post to their members.
A "Default newsletter recipients" option has been added to the "Email newsletter" settings screen and the publish menu updated to reflect the option. The free/paid toggles in the publish menu have also been swapped out for a multi-select style component that will cater to more complex member segmentation.
Prepring for custom products we'll change the overall layout of member forms. This commit has a component that's loaded when dev flag is on for the new layout with mocked product data.
