**Motivation**
Users should get help to write the category they need correctly
**Task**
When a user starts typing in the "Page in this category" field, autosuggest categories from the existing categories, as shown below. Selected categories also become tags.
**Background**
When using the extension, it must be possible to turn the category field on and off in the configuration, because not all wikis have their categories in [[ https://wikitech.wikimedia.org/wiki/Nova_Resource:Catgraph | catgraph ]], only most wikipedias.
The search field must behave like the [[ https://github.com/wmde/DeepCat-Gadget | Deepcat Gadget ]]: Query CatGraph with the given category names (ideally in the background while the user is still entering search criteria), get back a list of category names and generate `incategory:` keywords for each category returned.
