U can use Ajax if you need to make things without refreshing the page. Here is an answer to your question. hope its suitable. If you know ajax then you can always use this.

Here is my dropdown lists for rows.And these dropdown lists created with ngFor.When i select an option for any dropdown list, the selected value of all dropdowns change.Can anyone help me for this.
And this is my code.
I am going to assume, given that this is just images instead of posted html/ts code, that the issue lies in your ngModel for the select option. You are using the same model for all of them, thus any change would of course be reflected throughout all of the elements that use that model.
What you need to do is define a model for each one of those dropdown
your ngModel selectedStudent is the same for all the dropdowns. If the value changes, it will impact all the dropdowns
I have a requirement where my drop-down values in my select are an expanded div which has 3 lines. For example my options Could be something like below
Honda Accord
19'
Blue
--------------
Honda Civic
17'
Red
This is what my dropdown would look like when expanded. So instead of regular one line option I have a div with more detailed options. The challenge I am facing is when making my selection (I can correctly display the grid as above) my dropdown selection value shows as the context of the whole div. So for example my dropdown after selection would look like this.
[Honda Civic17'Red]
I am using Angular Material for my dropdown. Is anyone aware of a way to set the selection to another value than the option text? For example I would like my dropdown when selected to display [Honda Civic] instead of [Honda Covic17'Red].
Any help would be appreciated.
Thank you.
You can customize the display of the selected item using MatSelectTrigger. An example is provided here: https://material.angular.io/components/select/overview#customizing-the-trigger-label.
I am working on form array in which drop-down items have to load based on previous drop-down values but when I am adding a new same form dropdown values getting loaded based on the last dropdown values. Is there someone help me with this.
Using patch value and form control we can achieve this.
I've had a look around but not finding what I'm looking for, or I'm not searching for the right thing.
Language: ASP.NET
Basic idea of my problem:
2 pages - 1st page has 4 buttons, 2nd page has a dropdown box with 4 options.
If I press button 1 I want option 1 in the dropdown to be selected when I navigate, if I was button 2 then I want option 2 in the dropdown to be selected.
I still want to be able to change the value in the dropdown after navigation BUT the initial value should depend on which button I pressed.
Any help or guidance would be appreciated.
You can transmit index of button via ViewBag. And in the 2nd page you set the property "selected" for the item which have the same index with value received from ViewBag.
I am looking for a way where multi select list box should display as normal single select combobox but on click it should work as list box allowing multi selct like show below as in spreadsheet. I am looking for solution in CSS HTML and javascript rather than in Jquery.
You can't make an element behave like that, but you can make something that looks like a dropdown list, and when the user clicks on it, display a popup/popout with a select that allows multiselect (has the size property set).
you can do this by jQuery MultiSelect and here is the demo
