Preset: new multiselect for multiselection of same value with two separators

[skyper]

The new ​lanes scheme uses | as lane-separator but allows to use the same value several time plus uses ; as separator as normal separator (e.g. turn:lanes=reverse;left|left|left;straight|straight|right)

I would need to have a feature which allows me to select like a normal multiselect plus a button (shortcut) to add the current selection and the extra separator | and wait for the next values (next lane).

I'm not sure to totally understand your request, could you attach a GUI mockup of what you would like ? :)

Maybe, I have time for a mockup later on:

1. I need to specify a second separator.
2. I use a normal multiselect
3. I need an extra button next to "normal" multiselect" list.

Workflow goes like this:

1. select one or more values from list (reverse + left)
2. click on button
3. select one or more values from list (through)
4. click on button
5. select one or more values from list (through + right)
6. enter or tab or click somewhere else

Output using ; as first and | as second separator:

1. all selected values separated by first (reverse;left)
2. second separator
3. all selected values separated by first (through)
4. second separator
5. all selected values separated by first (through;right)

==> reverse;left|through|through;right

Hope you get the clue.

Is this feature request still relevant now that we're having a ​turn lanes plugin?

I did not try the plugin for years but according to the documentation it is only supporting some tags.

Currently, I am enhancing/updating Presets/LaneAttributes and I could really use it as the possible combinations are just too many, especially, if you have lot`s of lanes.

In the wiki discussion, ​osmwiki:Proposal_talk:Lines_arrangements#multiple_values, I noticed that some power tags use even a more complex value syntax. See ​osmwiki:Matrix_values for a general concept.

Looks like we need an option to open a new window and have the user to define the dimensions of the matrix and fill it with values from a predefined value list.
