Regularlab accordion or tab use 2 ways:
https://docs3.regularlabs.com/sliders/going-further/link-to-sliders
1• An automatic way
— When an accordion/tab is open, the url add automatically the title as anchor
Example: When {slider title="My Slider"} is open the url become —> www.mydomain.com/some/page#my-slider
2• An manual way by adding manually an “alias ” to the slider title that become an anchor
Example: {slider title="My Slider" alias="my-alias"} —> Url become www.mydomain.com/some/page#my-alias
Both can be targeted by a normal anchor link
<a href="#myanchor"> — for same page jump/open
<a href="mypage.html#myanchor">Linktext</a> — for another page jump/open
Any accordion or tab are made to categorize information NEED the possibility to be open/reach by anchor links. It not only give a powerful way to reach categorized information but also use by search engine as keywords/link.
On phone, Accordions and anchor links are an extremely powerful duo that permit to give top menus to users to reach and navigate tons of infos that are dissimulated in Accordions. Add to this “back to top Menu” anchors links well placed in accordions or in the flow of html and you get a fantastic fast navigating system that can make nice looking aerated page that can contains Tons of informations that can be reach in seconds.
Your builder (just like other editor like JCE) need to be able to insert anchor links and anchors and also your accordions & Tabs need to be able to use anchors links.
For me, personally that simple function if missing make your editor unusable professionally
