Would it make sense to have the Delete button next to the "Cancel" one rather than on the top?

I thought about that, but i found it more clear to have it on the top for many reasons:
1- keep it far away of cancel button to avoid clicking delete by mistake.
2- when i was trying to add the button in Modal pages, it was'nt strait forward and i found some issues with JS.

I think having the delete button in the bottom row with existing buttons sounds good. We could right align it to create distance. If it doesn't already, the delete process could also require a confirmation step to prevent accidental deletion.

waht about details page ?

Why we can't place "Delete" beside "Save" ?

Thnx for your comment, but I have reviewed the source code, and it seems like it is NOT possible to have the button aligned with others because of the **<form> ** tag Since Delete button should be wrapped in a separate <form> it can not be placed beside the "Save" buttons because they are already wrapped by thier <form> that include all Edit fields including "save" and other extra buttons. If i put the delete button beside "save" it will be like <form> inside another <form> which is not accepted case in HTML
