Dynamic Todo List Maker with Delete Button
Written by 10 April 2021
Forms are used in many advanced websites, and one of the important things in these forms is to create dynamic lists by users, in which the number of list items can be increased or decreased. In the following code, this possibility is provided and we have a dynamic todo list which creates new items by hitting a button. For each created item, we have also a delete and select buttons.
