Custom Input Buttons

There are already a number of different display options in the General Settings tab in Questionnaire Layout that can be selected as the input button in Input button style. Selecting the option „custom input buttons“ allows you to use your own image.

To do this, create an image (image set) according to the specifications below.
Upload the image into the survey project in Images and Media Files (do not use protected filing)
Choose this image for the Image set in the layout in Input button style → „Custom input buttons“.

After the layout is saved, the new input buttons can be seen in the layout preview (below).

Note: Many participants are used to the default input buttons on their operating systems. Different input buttons can annoy some people. Therefore, Windows makes a clear distinction between radio buttons (round) and checkboxes (square). Other operating systems do not make a visual distinction between the two.

Note: Sometimes custom input buttons appear a little pixelated/blurry on high-resolution displays (e.g. on cell phone devices).

Image Set Guidelines

All images required for custom input buttons are arranged in one_ image with a total size of 96 x 256 pixels in a 32-pixel grid.
The necessary items are arranged as in the grid displayed below.
The image is put to the top left in every cell. The number of grid cells displayed is determined in the side length option in „Questionnaire Layout“.

Radio button	Checkbox	Other
not selected default	not selected default	category in Extended Selection
selected default	selected default	not used
not selected focused	not selected focused	not selected
selected focused	selected focused	not used
not selected mouse over	not selected mouse over	not used
selected mouse over	selected mouse over	not used
not selected grayed out	not selected grayed out	not used

A completed image set looks as follows (only with a transparent background and without guides and frames)

Disable Selectively

The custom modification may be disabled for single questions or inputs. To do so, the input must contain the CSS class „preventCustomInputs“ or a parent HTML element must contain this class.

For complete questions, it's sensible to use a surrounding <div> HTML element:

html('<div class="preventCustomInputs">');
question('AB01');
html('</div>');

You may also place the question in the questionnaire via drag & drop and place HTML code elements before and after. The result is the same:

<div class="preventCustomInputs">

</div>

To display single inputs in the browser's default layout, JavaScript is helpful. This JavaScript code will prevent the layout modification for the input AB01_021, if placed below the question.

<script type="text/javascript">
<!--
document.getElementById("AB01_021").classList.add("preventCustomInputs");
// -->
</script>
