You can create a text field in your database and call it ‘hashtags’, for example. You can use JS split method to separate each individual hashtag to load them into a few text elements.
Then, in these text’s onClick() function you can set a filter on your dataset that shows only database items in which the hashtag field contains the same hashtag value.
**There is an easier way to set this up where you can skip using .split() and instead just create multiple hashtag fields in your database, which will allow you to connect them using the GUI in the editor.
