How to customize Admin UI in BBP Core plugin?
To customize Admin UI, you have to navigate to BBP Core > Settings. Then select Admin UI if it is not selected primarily. There you will see a set of settings for customizing Admin UI.
Hide bbPress post type
This option hides the default post types showing on the left-hand side of the WordPress panel. If you hide bbPress post types from the admin end, the following post-type menu options will be hidden. You can still access those using the Classic UI option from the BBP Core dashboard.
Choose default filter
By default, BBP Core Admin UI loads with ‘open topics’ as selected filter. If you want to select any other filter by default, you can choose that from here.
For example, in the following picture, the solved filter is selected by default.
Filters to show on admin page.
This option enables the admins to change visibility on Admin UI, if a button is selected and it is green, then the filter button will show up on the front end.
If you want to hide any filter button from admin ui, you have to click on that particular button and hit save. If that is the default filter, you have to change that to another filter manually.
