Settings

SIMPLE_SELECT2_THEME

Sets the project-wide default theme to be used by Select2 for all widgets inheriting from AutoCompleteSelect2Mixin. Can be overridden per widget using parameter theme.

Supported values are:

• None (or unset) will use theme "admin-autocomplete". This is the default.
• "admin-autocomplete" uses the theme of Django Admin.
• "bootstrap4" uses a bundled copy of Takashi Kanemoto's select2-bootstrap4-theme. Please note that this theme requires that you pull in Bootstrap 4 CSS and JavaScript assets in your templates somewhere yourself.
• "classic" uses the old classic theme of upstream Select2. Not much different from theme "admin-autocomplete".
• "default" uses the default upstream theme of Select2.

SIMPLE_SELECT2_WIDTH

Sets the project-wide default width to be used by Select2 for all widgets inheriting from AutoCompleteSelect2Mixin. Can be overridden per widget using parameter width.

For supported values, please check the official documentation of parameter width of Select2. By default, django-simple-select2 does not enforce any width on Select2.
