From your drawing, it seems that you want a text input field that also displays a progressively filtered dropdown list of items that have at least a partial match for the current text input. If this is the case, then my TiddlyTools `edit-list` macro (
https://tiddlytools.com/edit-list.html) can do this. Something like:
```
<<edit-list tiddler:"$:/temp/myinput" filter:"...some filter here..." find:and focusPopup:yes listwidth:fit>>
```
Where:
* `$:/temp/myinput` is a tiddler to hold your text input
* "...some filter here..." is TiddlyWiki filter syntax for specifying the desired list of items to match with
* `find:and` matches list items that have all the keywords entered into the text input field
* `focusPopup:yes` shows the dropdown list when the text input has focus
* `listwidth:fit` automatically resizes the dropdown list to fit the width of the current list items
enjoy,
