Pre-purchase Enfold questions

Hi

I have some questions re Enfold pre purchasing:

a) if i have a sticky menu that is a mega menu and sidebar menu too and both the sidebar and the main menu items have links to anchors will they scroll to the right place?

in other themes, the main menu scrolls to the anchor and it displays properly but the sidebar menu scrolls to the anchor incorrectly as it ends up under the sticky menu.

you also allow a second sticky menu under the sub header, can that be used to scroll to anchors properly if the main menu and secondary is sticky?

in my site, i want to do this due to diving into related content.

i) on the main mega menu, there would be a title ‘Products’. Which I click on that it goes to the first of the product pages, Prod 1. That page has your second sticky menu with the list of the products. Prod 1 is highlighted as I am there. In that page, there are sections with anchors. There is a sidebar menu that lists all the sections. Clicking on the section scrolls the page to there. And the section is highlighted if possible. If the scrollbar menu can scroll with the page that would be good. That section in am in should then remain highlighted. Can I do this or if not all of it, what can I in the standard 2017 Enfold.

ii) Can I use Anchors on the mega menu to directly jump to the section in a Products page as explained above?

iii) Can I use Buttons to jump to such an anchor on the same page or from some other page?

b) for a blog post, can I have related items AND recommended items that are specific posts I want to show links for at the bottom of the post? Can I show these in the exactly same style of image+text as https://www.helpscout.net/blog/?

d) do most theme customizations need php and a child theme or i can just add CSS (is there a place in the theme settings or options to add custom CSS) to do most of those. I don’t want to do any php coding at all if possible..

e) Re deep linking, you say that is used on accordion/toggle. Can it be used with Tabs and Tabs section too so the right tab is reached just as the right toggle is opened with deeplinking URL?

f) Do you have a drop down ‘action bar’ or such sliding element above the header. Usually a small strip you click on and a curtain slides down that holds widgets, etc.

Thanks
