LFGAdvancedFilter - Dungeons - is an addon which adds dungeons and role filtering options to the premade group finder.

After selecting Find a Group in Group Finder > Premade Groups > Dungeons, you should see a Filters button to the right of the search field.
Clicking this button will reveal a list of checkboxes for dungeons and roles to be included in the search results.

You can hide results with dungeons that don't suit you and set your role to track the corresponding free slots for the role.

To cancel the action of the role filter and view the full list of results, you must turn off all checkboxes for roles.

The addon does not work with the "Arena Filter" addon or any other addon that modifies LFGListLanguageFilterDropDownFrame.

This is my first add-on and it was inspired by the "Arena Filter" addon in terms of using a language filter, but differs in implementation and logic of work
