True/false checkbox for Boolean fields

If you have a field with a Boolean data type, QGIS assigns the checkbox widget type by default. It is also possible to use it for fields with other data types.

1. Right-click on a layer, select Properties and go to the Attributes form tab.
2. In the list of Available Widgets select the field you want to work with (here: checkbox).
3. In the Widget Type tab, the Checkbox widget should be set by default (if not, select it from the drop-down menu).
4. Apply the changes. Don't forget to save and sync your project!

Checkbox with custom values (yes/no)

You might want to use the checkbox with custom values, such as Yes/No or On/Off. This is possible for fields with Text (string) data type:

1. Right-click on a layer, select Properties and go to the Attributes form tab.
2. In the list of Available Widgets select the field you want to work with (here: checkbox-string).
3. In the Widget Type tab, select the Checkbox widget and define values for the Checked and for the Unchecked state. Here we use Yes and No.
4. Apply the changes. Don't forget to save and sync your project!

Similarly, you could set up the checkbox widget for fields with integer data types and use numerical values, e.g. 0 and 1, for the Checked and for the Unchecked state.

In the mobile app, the checkbox can be easily toggled on/off.
