I am also after method of expanding the entire subtree of the selected node. My preference is for keyboard shortcuts. Something like the '*' (expand all), '+' (expand one level), '-' (collapse) keys that the old XTree Gold program used would be nice as they are all next to each other on the numeric keypad and can be easily operated while navigating through the tree using only the keyboard.

Also, the current keyboard shortcuts (left/right arrow) are not documented in the Dolphin Handbook.

Throwing in my support for this.

It seems we would need the following:

1. Button to expand selected folders
2. Keyboard shortcut for expanding selected folders and none of their children
3. Keyboard shortcut for expanding selected folders and all of their children
4. Keyboard shortcut for collapsing all selected nodes

I would implement this via a popup menu.
In other words, Dolphin would be in tree view mode.
The user right clicks the folder.
A popup menu opens.
Click on Expand This Folder.
or
Click on Collapse This Folder.

I don't think there is a need for a keyboard shortcut for this feature.

I guess this includes the possibility to expand/collapse ALL folders including subfolders from the folder we selected first.

I do not understand the logic about not having a shortcut to this feature.
I really think it would be great if it was made with a shortcut available.
I would use this feature multiple times every hour of the work day and to not have a shortcut to it would not be so nice.

Why shortcuts:
A lot of people have multiple hi resolution screens meaning mouse movement are on high sensitivity. 
Then to select from a menus many times during a workflow generates more tension in shoulders and arm because you tense up to do micro movements. Many users wants therefor to have shortcuts for repetitive tasks to take load of the mouse arm.
Also in general the less mouse you need to use the less arm and shoulder fatigue. 

e.g. select the  directory and press 'd',for just showing the directories, to collapse all sub-directories and perhaps 'f' to expand then (d and f being next to each other and on the home row. If you use your mouse in the right hand you do not need to drop it and can directly select the directory you want). Vs right click the directory then move the mouse to the right place.

This would be nice:
Right click directory opens menu > collapse (show the shortcut-key in the margin)
Right click directory opens menu > expand (show the shortcut-key in the margin)
Keyboard shortcut for expanding selected directory and none of their children
Keyboard shortcut for expanding selected directory and all of their children
Perhaps for nodes as well. but I do not know what a node is so...

The left/right arrow shortcuts for expand/collapse in 23.04.02 work great. It would good to also get a short cut for "expand all", and to make the keyboard shortcuts configurable.

Great to here.

I will close this bug then, feel free to open a new for your new suggestion.

> It would good to also get a short cut for "expand all",

It exists sort-of "Ctrl+A" then "Right" ><

Would you case to suggest a default shortcut?

> and to make the keyboard shortcuts configurable.

That would be down the road we have a lot of hardcoded shortcut in the view currently, it won't be easy to change this, meaning requiring a lot of effort and be error prone.

<Ctrl-A>, <Right> does not do what I had in mind. By expand all I mean for the currently selected folder, recursively expand all subdirectories below it. You could use a shortcut like <Shift-Right> or <Ctrl-Right>. It would probably need a limit on the maximum depth and/or number of files in case someone does this on a directory with a huge number of files in the subdirs. It could be similar to the Folder Size display depth limit setting.

For that, there is a way, using the keyboard up/down keys to select the folders you want while holding SHIFT, then while keeping SHIFT held keep pressing right and the sub-folders selected will expand one level at a time.

You can open a specific bug for that.
I tried to add a specific SHIFT+Right behavior while implementing the fix but our code can't accommodate this ATM.
