How can I “remember” a value such as using a parameter?

I capture a value from this.items.length from
```
{{#each items}}
```
and I would like to “remember” this value for comparison in other areas of menu.hbs.

Is there a way of setting a parameter with this value without messing up “this” from each items?

I am trying to distinguish the first and last dropdown-items within a menu.

If I can crack thus nut, I am done creating my custom template.

Cheers!!

Hi,

I suppose that it is also connected with: https://forum.getpublii.com/topic/need-help-capturing-the-first-and-subsequent-menu-items-of-a-dropdown-in-a-menu/

Please consider using custom @data variables like: @index, @first or @last described in: https://handlebarsjs.com/api-reference/data-variables.html

If it won’t help – did you consider using CSS selectors like last-child last-of-type etc.? 🙂

Yes it is related to https://forum.getpublii.com/topic/need-help-capturing-the-first-and-subsequent-menu-items-of-a-dropdown-in-a-menu/ and https://forum.getpublii.com/topic/what-am-i-missing/.

The good news is, I have a solution. But the system did not allow me to post the code for a solution for others to follow. Can you help me on this?

Thanks for the reply.

Cheers!!

I suppose that your code contains some fragments which are treated as unsecure by our WAF :/

Are you saying your WAF did not like what it wiffed?

Fortunately, there is another option so here it goes.

In a nav menu

home

articles

_article 1

_article 2

_article 3

contact

I needed to identify nav links that are not dropdowns (home, contact), the top of a dropdown (articles), the first and last dropdown items (article 1 and article 3).

I used this.items.length and this.level for much of it, but I needed to remember this.items.length using a parameter before processing dropdown items.

I wrote a helper and then modified the menu.hbs.

Here is the code. (ugly of course)

It all works now!

I am hoping my code helps inspire others.

Cheers!!
