Seo optimizations

Hi,

I'm working on my project seo optimization and I would like to share some warnings reported by google chrome lighthouse, so maybe in the next mdb versions the code could also have these optimizations.

• mdb-select-2 give this issue: [aria-*] attributes are not valid or misspelled

this is the html code generated in the page:

<mdb-select-2 _ngcontent-serverapp-c172="" placeholder="seleziona i profili" class="ng-tns-c95-0 mdb-select ng-untouched ng-pristine ng-valid" aria-multiselectable="true" aria-haspopup="true" aria-disabled="false" aria-expanded="false" aria-role="listbox">...</mdb-select-2>

• mdb-tabset give this issue: Links are not crawlable : earch engines may use href attributes on links to crawl websites. Ensure that the href attribute of anchor elements links to an appropriate destination, so more pages of the site can be discovered.

  < a href="javascript:void(0);" class="nav-link active waves-light ng-star-inserted">Video

Regards

Marco
