    Increase size of text box field

    Asked by thedoor on July 01, 2015 at 12:33 PM

    I manually edit them to make them bigger and the form then Auto-saves. But when I leave the form and come back, it is back to the original, small size. What do I do to ensure my changes stick?

    You can increase size of your text box fields by Injecting Custom CSS. To do that inside of your Form Builder select Setup & Embed tab, then click on Preferences, then select Form Styles tab and inside of Inject Custom CSS field at the bottom of existing code paste this code:

    .form-textbox {

    width : 150px;

    height : 18px;


    You can also change size if text fields inside of Form builder by increasing Size.

    Hope this will help. Let us know if you need further assistance.
