I want to create a search form in amp page the form and displat returned data is working fine, but i wanted to know how to add

1. load more button
2. filter popup

I tried following implementations but didn't workout

1. added form inside the submit-success element but it generates errors
2. added amp-list but cannot use post method and with get method also i am not able to append data with some pagination.
3. tried to submit form externally using tap event but no use

any help would be appreciated
