Detailed Description

This offers a combobox with autocompleter that allows selecting features from a layer.

It will show up to 100 entries at a time. The entries can be chosen based on the displayExpression and whenever text is typed into the combobox, the completer and popup will adjust to features matching the typed text.

Since: QGIS 3.14
