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"; } ?> />
<label for="ecsall">Toggle All</label>

<input type="checkbox" name="ecs02" id="ecs02" value='development-opportunities' <?php if ( $ecs02 == "development-opportunities" ) { echo "checked"; } ?> >
<label for="ecs02">Development Opportunities</label>
<input type="checkbox" name="ecs03" id="ecs03" value='gigaplant' <?php if ( $ecs03 == "gigaplant" ) { echo "checked"; } ?> >
<label for="ecs03">Gigaplant</label>

<label for="ecs04">Innovation Hub</label>
<input type="checkbox" name="ecs05" id="ecs05" value='networks' <?php if ( $ecs05 == "networks" ) { echo "checked"; } ?> >
<label for="ecs05">Networks</label>
<input type="checkbox" name="ecs06" id="ecs06" value='university-and-colleges' <?php if ( $ecs06 == "university-and-colleges" ) { echo "checked"; } ?> >

<button id="search-submit" class="button">Apply Filters</button>
</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.
