As part of T167384, an "advanced filters" section was added at the bottom of the regular filter panel. Currently it is available as part of the floating bottom bar where the link to provide feedback is also present.
In order to avoid the advanced filters to take too much prominence over the regular ones, these should be provided at the end of the list. The mockups below capture how these appear in different situations:
|Not visible initially at the beginning of the list| Visible when scrolling to the end of the list|Shown after the indicator of no results when filters cannot be found|
|---|---|---|
| {F8530541} | {F8530543} | {F8530545} |
This gif captures the scrolling interaction:
{F8530523, size=full}
(The screenshots reflect a local modification where the active filters element was moved right after the "no results found" message in the HTML).
