Hi, I need some assistance with my coding. I have a page where user can edit the data that have been created. Currently, I am facing the following issues
1) Form is updated but at the main page, it is not updated (refer to image 1)
2) If I just want to edit the type, there will be duplicate (refer to image 2). But if I reselect the brand, the type will not have duplicate (refer to image 3). And for example, initial brand is "Honda", I need to select "Toyota" first then select "Honda" then the type will work.
Below is my code for the all car page
Below is my code for the update detail page
Below is getBrand page
