Take a look at:
Justin was as usual very helpful.
Maybe you can add your use case to the Git Issue to try get some traction?
From what I have seen the variable is not really set, just a default value used till it is set.
Nothing is set. The OR statement simply chooses the variable value if it exists, and if not, it chooses the secondary value you provide. There is no way to set a variable that is not one of the widget variable actions.
Nope. Assignment statements are just not supported by the expression parser.
That’s why I said you will have to make your expressions a little more complicated. You simply have to replace every instance of “vars.buttonIndex” with (vars.buttonIndex || 0). There are other expressions that will achieve the same thing, but this is the cleanest.

Hi guys, I played a bit with the f7-swiper in combination with the oh-repeater and found a more dynamic solution, as I think.
Only prerequisit is to set a tag “Floor” to the floor group items and a tag with the floor group name to the rooms accordingly.
here is the code snippet:

I have not added styles for selected buttons or any other fancy stuff, just wanted to show a poc…
Edit : If you want to have shorte Names for the buttons, you can use additional metadata (uiSemantics) and add a shortname…

I hope that, in addition to having this published to the Marketplace, that some effort is being made to capture what has been learned in this thread to build a tutorial, augment the official docs, etc. There is a lot of great effort and new ground being broken here and I’d hate for it to remain hard to find.

@hmerk Merci Monsieur! Hope that @Nic0205 will find some time to investigate deeper.
I have strong inerest only for
Fancy stuff and me = 
Thank you!
Dear @rlkoshak ,
What we do obviously belongs to the community. I’m sure that @Nic0205 agree on that.
From my side, the final design with the graphical description of all the functions will be published here in the form of a manual: Many of them have already been posted and I’ll continue to post all their updates. Nic does the same with coding.
But I think that even as a plan or development we are looking for our steps and it is still early to “officially” post the project…
The structure we follow consists of two areas:
1. Navigation
NavBar (Header)
Tabs (footer)
2. Widgets
a. Lights
On-off Light
+Brightness
+Ambience
+Color
Mayby 4 Widgets: Will be under investigation if we can create a “smart” that will cover all cases:
b. Rollers
+Venetian Blinds
c. HVAC
d. Security
e. Weather
f. Scenes
On the design side, I dare say we are very close to the first version in both areas.
When Nic is finished, and if he agrees, I commit to create a combined guide (Programming + Design) and post it in the format you indicate.
I want to say here that the important thing is the work that Nic is doing -with the tremendous help and guidance of @JustinG @hmerk - and not mine, without wanting to downplay the design part.
Thank you for your post!
@JustinG
Hmm. I tried it - but with this:
filter: (loop.HomeMenu_idx >= (vars.buttonIndex || 0)) && (loop.HomeMenu_idx <= (vars.buttonIndex || 0)+2 ) )
in my above posted code the filter does not work.
I thought with the filter like I described I would limit the HomeMenu to 3 (0,1,2) but all HomeMenu-Entries are shown.
if I replace it with a fix number:
filter: (loop.HomeMenu_idx >= (vars.buttonIndex || 0)) && (loop.HomeMenu_idx <= 2 )
It filters correct. But not with the variable…
Very cool - it would be great to see things coming together!

I totally agree with Dimitris!
As a noob in all these things I know now how hard it is to start - of course we and I will share the experience. I think we are part of the community !

As promised, I tried to combine both approches to get it more dynamic.
Prerequisits:
My model is based on a floor/room/equipment structure. All floors groups (gAttic, gGroundFloor, gFirstFloor and gBasement) have a tag "Floor. Rooms within the floor (gAttic has Office (gOffice) and Guestroom (gGuest), have a tag with the floor groop (Office has tag gAttic).
Therefore, I removed the array configuration and hardcoded the top level menu array to Home, Floors and Rooms.
Here is the result:

Wow. This is on a other level. Congrats to Nic to have achieved this challenge.
Great help also from other guys involved in this!

Wow - looks cool and makes the code much “cleaner”.
But to be sure - the posted code is without the swiper approach.
@All: Should we integrate the swiper or go further with this great state after solving the “variable Index” challenge?
@Hmerk: I agree with Ruben! That’s really the next level!
No, I did not clean that much in the code, just a few lines. But removed the array configs.
No, still the segmented approach. But we can try this with the swiper approach as well. Benefit would be that it could handle long names better, as I was wrong, uiSemantics can not be set on group items, so no easy way to get short names lige EG, FF, SF and so on…
Thanks, glad I can help
on my device (iphone x) when i click floors or rooms, sub menu is not shown.
for floors i only have “scale” sub menu.
i think this is normal in this version, but i would like just to report in case is not known …
Did you add the tags as decribed to your floor / room groups ? If not, the code does not work…
yes, but sure i’m missing something.
Taverna (gTaverna) is member of gCasa.
Taverna is set as Floor as Semantic Class.
Taverna is shown as Floor in widget.
Taverna has 2 memebers: Bagno Taverna (gBagnoTaverna) and Tunnel Taverna (gTunnelTaverna).
Both defined as Room as Semantic Class.
Both not shown in widget.
what’s missing?
You need to add a tag “gTaverna” to Bagno Taverna and Tunnel Taverna.
