function _openlayers_settings_form in Openlayers 6

Abstracted Form Elements for OpenLayers Settings

Since the Domain module would like to know about our form elements, we abstract them into this function so that we can re-use code properly.

Return value

From array

2 calls to _openlayers_settings_form()

openlayers_admin_settings in includes/openlayers.admin.inc

It is suggested you use a compressed version of the JS file as Drupal will not aggregate it.
