multiple rows in 1 dropdown

Hi, i’d like to know if it’s possible to add 3 different rows elements inside 1 dropdown?

Each column of the database is a keyword affected to an item for example it could be an apartment to sell which is “calm” (column1) “bright” (column2) “good location” (column3)

Is there a way for user of the website to see all the 3 columns choices in one dropdown.
Imagine the user would like to see only the “calm” apartments or the “bright” ones

For now i only can show the elements from the column 1…
Thanks for your help (i m totally a noob in JS) )

export function dropdown1_change(event, $w) {
wixData.query(‘Listing’)
.contains(‘hashtag1’
//would be perfect if i could add something like: &‘hashtag2’&‘hashtag3
, $w(“#dropdown1”).value)
.find()
.then(res => {
$w(’#repeater2’).data= res.items;

});

}

See this example:

Multi-Select Dropdown

Create a dropdown menu with checkboxes and search a database using multiple filters.

This example uses a repeater to “mimic” a multi-select dropdown.

thank you very much for the clue !
