I've had some success at creating drop down lists for attributes in QGIS 3.16 using the Attribute Form option in Layer Properties, as shown here:

 Creating multiple select dropdown list in QGIS

My problem is that whenever I remove the layer and then bring it back into QGIS, my drop down lists are not an option in the attributes. They have gone!

Could anyone give guidance to how to make drop down lists permanent, so when I export a shapefile or bring it back into QGIS, the drop down lists remain?
