Make ItemList multi-select easy on mobile devices

[ondesic]

Describe the project you are working on

Inventory list on android device

Describe the problem or limitation you are having in your project

Currently the only way to multiselect an item in an ItemList is to press the SHIFT or CTRL button first before clicking on the item. The problem is, you can't press SHIFT or CTRL on a mobile device and so you lose the cross-platform of a Multi-Selectable ItemList.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

By adding a way for the ItemList to be multi-selectable without SHIFT or CTRL, now all mobile devices or those without a keyboard can use a multi-select ItemList.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

There are a few ways this could be addressed.

1. Add to the SelectMode enum a SELECT_MULTI_ONLY mode. This mode makes the ItemList operate as if the SHIFT or CTRL is pressed all the time.

2. Make a signal that gives the index of the selection WITHOUT selecting the item. This way the uses can choose to use the Select(int idx, single = true) to make the selection manually depending on the platform.

If this enhancement will not be used often, can it be worked around with a few lines of script?

Multi-select is a basic function/use of an ItemList and will be used frequently.

Is there a reason why this should be core and not an add-on in the asset library?

Single and multi-select is a basic feature of an ItemList node. My project's biggest feature is that it is cross-platform. I use many multi-select ItemLists in my project to organize inventory. To the end user, the ItemList's basic select ability needs to operate the same on the Desktop as the mobile. Any mobile developer hoping to create a game with an ItemList will run into this problem if not fixed.

I think the proposal of a toggle mode (#6371) would solve this, but you would have to select each item one at a time.
If you think this is too much work for the user, I could start implementing an additional SELECT_MULTI_ONLY mode.

A multi only mode would be great.

I have implemented the new mode, but now I have noticed that it is impossible (with my current implementation) to select items that are not next to each other. @ondesic Do you have any idea how this new mode should behave in these situations?
