To filter NFTs by Collections, go to the 'Artworks' page, click on filter, and find the 'Collections' filter. We have added a search bar for this specific filter to make it easier for you. You can look for a specific collection by entering its name or a keyword related to it in the search bar. Once you start typing, the system will suggest collections that match your input. Select the collection you want, and the page will show only the NFTs from that collection. You may add other filters to narrow your search more.
