Custom form (or <div class="modal-dialog">) creation (newbie question)

[igrp]

Hi !

Could someone give a clue (code example or similar source code in EspoCRM files) how to show a custom form (or preferably <div class="modal-dialog"> - like modal editor) with set of fillable fields and action button.

Generally I need a simple form where users can put some data and click on "action" button.

Thanks in advance!
