Hey there, @kyllaz ??
Sure! While it’s not possible directly from HappyForms UI, you can definitely achieve this by applying custom CSS to submit button. For example, if your icon is the image, you can set it as a button background like this:
input[type=submit].happyforms-button--submit, input[type=submit][disabled].happyforms-button--submit {
background-image: url(URL_TO_YOUR_IMAGE);
background-repeat: no-repeat;
background-position: left center;
}
Hope this helps!
And just a quick heads up: We’re taking a few days off over Christmas. So if you don’t hear back from us right away, just know we will get back to you Jan 2 ????
