Hi Tristan,
Did not get it working based on the hints above. For now I have a applied a work-around. I have created a textfield (field key: “active”) in my database which I populate with “y” and “n”. y stands for checked box an n stands for an unchecked box. Based on that info added this line to the code:
.eq(“active”, “y”)
So my reset code now looks like this:
// Reset button code:
$w(“#button12”).onClick(() => {
$w(“#dropdown1”).value = null;
$w(“#dropdown2”).value = null;
$w(“#dataset1”).setFilter(wixData.filter()
.eq(“active”, “y”)
);
Frustrating I could not get the filter working on the checkboxes, but for now I can move on. Please drop me a note if you find the proper solution.
