I want to select some features and edit their attribute but the toggle editing button wouldn't activate at all.
Features - from csv file with Latitude and Longitude values
Coordinate - EPSG 4326
Map - shapefile of South Korean peninsula
These are features on my map on QGIS 3.22.0
I selected one of the features.
When I open the selected feature’s table, the toggle editing button would not activate.
CSV files are not editable, save your layer to a geopackage and edit that.
