You should t write data-toggle  modal  in the element which triggered the modal  like a button   and you  manually can show the modal with       myModal   modal  show      and hide with       myModal   modal  hide

The same thing happened to me  I wanted to open the Bootstrap modal by clicking on the table rows and get more details about each row  I used a trick to do this  Which I call the virtual button  Compatible with the latest version of Bootstrap  v5 0 0-alpha2   It might be useful for others as well  See this code snippet with preview  https   gist github com alireza-rezaee c60da1429c36351ef4f071dec0ea9aba Summary  let exampleButton   document createElement  quot button quot    exampleButton classList add  quot d-none quot    document body appendChild exampleButton   exampleButton dataset toggle    quot modal quot   exampleButton dataset target    quot  exampleModal quot      AddEventListener to all rows document querySelectorAll   exampleTable tr   forEach row   gt        row addEventListener  click   e   gt              Set parameteres  clone row dataset          exampleButton dataset whatever   e target closest  tr   dataset whatever            Button click simulation           Now we can use relatedTarget         exampleButton click                All this is to use the relatedTarget property   See Bootstrap docs

In order to manually show the modal pop up you have to do this      myModal   modal  show      You previously need to initialize it with show  false so it won t show until you manually do it       myModal   modal   show  false     Where myModal is the id of the modal container
