Use dropdown (without duplicates) with dataset and repeater

Hi all,

I am new to Corvid and having a hard time in getting a simple Dataset with a repeater working with one dropdown (without duplicates).
When I follow the instructions on the Wix site I get stuck somehow.

Dataset is really simple to reflect the stock with columns: “brand”, “size”, “description” & “pics”.
I want 1 dropdown to select the “size”. Brand and others should be in the repeater but not selectable via a dropdown.
I am so far. But I copied in a few different corvid codes to remove duplicate “sizes” and I want to use a reset button.
Is there somewhere an complete full instruction for noobs to get this done? Its frustrating like crazy since Wix offers so many tools for creating a nice website but a simple request like above without coding seems to be much too difficult.

Thanks for helping me out.

$w.onReady(() => {
$w.('#dataset1').onReady(() => {
$w('#dataset1').getItems(0,1000)
.then(r => {
let options = r.items;
options = options.filter((e,i) => options.findIndex(q => q.size === e.size) === i );
options = options.map(e => ({label:e.size, value: e.size}));
options.unshift({label: "All", value:"all"});
$w('#dropdown1').options = options;
})
})
})

Thanks J.D.
The dropdown removes duplicates, that’s solved.
However, when I select any of the values in the dropdown, the repeater doesn’t filter the selected value. It returns on top of the repeater the selected value but below in the repeater all others are there.
I want the repeater only to show the value which is selected in the dropdown (size).
Might be a wrong setting from me?
Thanks.

So you have to create a filter (either connect the dropdown to the repeater or filter using code)
