To output the URL with the var string use a confirmation page in gravity forms and pass the variable, something likie this
ecs01={Categories (Company):1.1}&ecs02={Categories (Development Opportunities):1.2}&ecs03={Categories (Gigaplant):1.3}&ecs04={Categories (Innovation Hub):1.4}&ecs05={Categories (Networks):1.5}&ecs06={Categories (University and Colleges):1.6}Or use your own form element like this:
<script language="JavaScript">
function toggle(source) {
var checkboxes = document.querySelectorAll('#cat-form input[type="checkbox"]');
for (var i = 0; i < checkboxes.length; i++) {
if (checkboxes[i] != source)
checkboxes[i].checked = source.checked;
}
}
</script>
<form method="get" id="cat-form">
<fieldset>
<input type="checkbox" name="ecsall" id="ecsall" onClick="toggle(this)" <?php if ( ! empty($ecs01) && ! empty($ecs02) && ! empty($ecs03) && ! empty($ecs04) && ! empty($ecs05) && ! empty($ecs06) ) { echo "checked"; } ?> />

</form>Note: the ‘Get’ method shows the string in the URL useful for copy and paste and the ‘post’ method hides the string which maybe useful if you want to have a cleaner URL.
