We refactor the following inputs to use a `placeholder-shown` CSS selector to
show/hide the close button, rather than custom JS logic:
- Filter topics field in the left sidebar
- Filter direct messages field under direct messages
- Stream message topic
Fixes#22113.
The search will only be visible when in the `more conversations`
view. Once we click `back to channels` and close the
`more conversations` view, the search will clear and the search
box will disappear.
We've chosen `pm_list_data.get_conversations` as the function
to which we will pass our search term. We could have technically
found the value of the filter element via JQuery in pm_list_data,
but pm_list_data does not handle any JQuery and we should keep
it that way.
`pm_list_data.get_list_info` also accepts the search_string so that
the info it returns in expanded view is accurate.
We've also added some code to `click_handlers` to make sure that
clicking the search input does not bring us into the DM narrow.
We clean up unnecessary nesting in this commit and replace one
usage of `#direct-messages-sticky-header` with
`#direct-messages-section-header`. Since `.direct-messages-container`
was being used along with `#direct-messages-sticky-header` at multiple
places, just removing the nesting would break those selectors. For those
selectors, they have been refactored to just look for
`#direct-messages-section-header` instead. `.direct-messages-container`
specific selectors still exist but they apply to both instances of
`.direct-messages-container`, the DM header and the DM list.
While the TODO comment we deleted in left_sidebar.css says we need to
rewrite both show more and show less button to grids; show more was
already a grid.
There have been some very slight changes in the actual size of the back
to channels row; those changes make the row more consistent with the
rest of the left sidebar rows in terms of sizing.
We've introduced a new class called `.hide-more-direct-messages-text`
that applies the same properties as the `span` selector used to. We are
using a class because of better performance when selecting, see
https://chat.zulip.org/#narrow/stream/6-frontend/topic/CSS.20selector.20performance/near/1845719
for more info on the why,
The `font-size` was moved inside the above class, so that when setting
the line-height of the anchor component, the `em` refers to the normal
font size and not the smaller font size for `back to channels`.
We've moved the link inside `.direct-messages-section-header` and most
of the grid properties are inherited from that element.
This is a preparatory commit to introduce DM filter in #30332.
Earlier, in left sidebar, clicking on followed topic icon would narrow
to the topic.
This commit introduces the ability to open topic status menu from
left sidebar from followed topic icon.
