Add padding to Select checkboxes in pre-defined Search component

I like using the Predefined “Is” option for a Select field type to show checkboxes for all available options.

But the format adds a single space between the checkbox and each option, and no space between each option and the next checkbox. I would like to be able to specify padding on the left and right of each option. For example, in the screenshot below, I have selected A10, but the checkbox is actually closer to A09. So I might want to remove the space before A09 and add one or two spaces after A09. It’s confusing to users the way it is now.

please try the following:

.tb-checkbox {
margin-right: 5px
}

You can play with the number of px to optimize the distance.

Above code you put in the CSS-tab of your page

@Peter Works beautifully! Thanks so much!
