I am having trouble trying to find out how to change the Yes/No Dropdown to a Checkbox while in quick edit mode. I am on a SharePoint Online list and have tried a few different things without any luck. See the attached picture for more clarification.
Something along the lines of this following image I created real quick. Each row would have a checkbox the user can just checkmark straight from Quick Edit mode.
By default "Yes/No" column type values will be displayed as drop-down, its by SharePoint design. If you want to display Yes/No values in checkbox then change the column type to choice, follow the below steps,
Go-to list settings
edit your Yes/No column --> change the column type to choice
Enter Yes and No as choice values
Select Display choices using: Checkboxes (allow multiple selections) , if you want single selection, you can select radio button or dropdown.
Click "OK", now in quick edit values will be displayed using checkbox.
The above change did not affect the data in my list.
