E.g. topics you're subscribed to, topics you've participated in, etc.
This ticket describes "quick filters" that provide basic filtering options. For advanced filters, see T99875.
## Entry points
Quick filters are shown in two locations:
- **When accessing the search bar.** Quick filters are shown when the user input is in the search bar but there is not a search query yet. As soon as the user types, quick filters are no longer shown.
{F164846}
- **At the bottom of the table of contents.** It is an always visible footer for the table of contents (even if the list of topics needs scrolling, the quick filters are visible).

# Filter mechanism
Regardless of the location, the "quick filter" component is the same. It works as a quick way to apply the common filters and it provides an option to access the advanced search panel in case more options are needed.

* When a filter is active, it appears in the search bar.
** Active filers have an "X" action to remove them.
* When a filter is active, only topics matching the criteria will be shown in the board and the table of contents.
** The quick filter bar will show an indicator of how many topics are shown and the total to communicate that there are more topics than those shown.
** When several filters are applied, only the topics meeting **all** of them are shown. That is, an "AND" approach is followed when combining filters.
## Filter actions

- **Users:**
-- Participant. The user has participate din the topic in some way (the topic was created by the user, or was mentioned).
-- Mentioned. Topics the user has been mentioned.
- **Starred.** Topics the user is subscribed to.
