I have multiple Dropdown list. Each dropdown have values from 1 upto 10.
In first dropdown list, if the user selects value 2, then automatically the value 3 will be shown in the second dropdown list.
So in the end, if the user selects a value from the first dropdown list, I must show the value, incremented by one on the second dropdown list.
How can I do it in Angular?

Found in the gem (write_xlsx) how to make the cell be a dropdown list but receive one value .... What I want is how to make the cell a dropdown list with the ability to choose more than one value
I have a column that has dropdown list with data validation, and its applied infinitely down that column. So I have lots of cells with the little dropdown arrow which is annoying.
Is there a way to remove that dropdown arrow....IF say "Date" or "Name" column is empty?
I want the drop to to show only when I have started inputting data to that row, I will never start with the drop down, I start with date. So ideally, as soon after entering the date, the dropdown arrow appears.
Can that be done? Thanks!
You can remove the dropdown arrows by unchecking Show Dropdown List in Cell on Data Validation dialog:
This will show the dropdown list only when you start entering data to the cell.
I have created a component of custom drop down list, for re-use it in another components like form.
I am using two components
1) Form (Parent Component)
2) drop-down (Child Component)
Form component has two drop-down list first is Country Name list and second is Cities Name list. The data is sending from parent component to make the drop down-list.
The expected behaviour is as follows.
1) On clicking the Country input field, the list of Country Names drop-down should be open
2) On clicking the Country input field again, the drop-down should be hide
3) On clicking any where in page the drop-down should hide.
4) On clicking another drop-down input field the relevant drop-down list should be open and same time other drop-down should be hide.
Every-thing is working fine except following.
If Country down-list is already opened and same time I click on Cities drop-down input field the relevant Cities drop-down get opened.
But the Country drop-down list is not getting hiding. The expectation is Country drop-down list should hide.
I want to get the selected item ids in a String array (preferably). How to get the selected item ids when multiple items are selected?
The documentation is often helpful :-)
You can select an item with the corresponding setValue() method. In multiselect mode, the property will be an unmodifiable set of item identifiers. If no item is selected, the property will be null in single selection mode or an empty collection in multiselect mode.
So after casting comboBox.getValue() to Set<?> you can call toArray(new String[0]) to get the desired array.
I have a dropdown list in which I select how many people are going to a party. When the user changes the value of the dropdown list, I want as many fields as the number selected to appear and hide the rest.
But I don't know how can I hide or delete fields because I don't know their index.
Yes you will need to have the fields you want to hide as a global variables.
You will also need to get the value the user has selected and use that to work out what fields should be removed or added.
One way would be to add all the fields in order to a vector or an array when the screen is initialised. Once the user has selected a value you could iterate through the fields and use the current index of the list and the user selected value to work out if the field should be removed or added.
If you have the field objects, then use Field.getIndex() to find the index of each field within its manager.
