Change position of button “check”

This might be solved with some custom CSS, but depends on the theme you are using.
Could you post a link to your page?

Ah ok, oh yes, i don’t see other alternatives. Aren’t you going to propose a function dedicated to the “check” button?

For now, being on a page not yet published, i can’t turn the link to you.

How do you want the elements to be arranged?
One possibility is to use the mobile view, adding the following custom CSS:

.wp24-dc form > div,
.wp24-dc .dc-form > div {
	display: inline !important;
}

.wp24-dc form input,
.wp24-dc .dc-form input,
.wp24-dc form select,
.wp24-dc .dc-form select {
	width: 100% !important;
	margin: 5px 0 !important;
}

.wp24-dc form span.dot,
.wp24-dc .dc-form span.dot {
	display: none !important;
}

.wp24-dc .table-row br {
	clear: both !important;
}

.wp24-dc .table-cell {
	float: left !important;
	padding: 0 5px !important;
}
