There are some column filters that are search box type, where you place a text whether in part of full. It will return values that contains the text value entered.
Example:
search box value is admin
Returned values:
Admin, administrator, etc.
Other column filters use a drop-down type, where the return values that can be multi selected.
Drop-Down selected:
admin, foreman, planner
Returned values:
Admin, Foreman, Planner
It would be better if there is a way to use the multi-filter search box type and be able to select multiple parameters using search values and delimiters such as commas, semi-colons, colons, etc.
Example: multi-filter search box:
Admin, Project Manager
Return values:
Admin, Administrator, Project Manager, etc.
