The "Site/Administrator" select is a bit a special case because you have one of it active all the time. YOu don't have a "select location" entry. I think you could as well do it as a submenu (it used to be, or not?).
It certainly doesn't play nice together with SearchTools. Or is there a way to ignore that for the "popup" of the Search Tools? @phproberto

That need to be a static filter (changeable by users but always with a value). You can check how it's done in the menu manager which uses an override of the searchtools layout to display the static filter before the search box.

Here is my Pull Request FOR MODULES only. Please help testing!
#6682

I don't have time for Plugins Manager. Maybe you should better close this issue and open a new one, just for Plugin Manager(?)

@Bakual @phproberto Thank you for your hints!

@phproberto Maybe this is a chance to test your PR #6677 ?

Hi @bertmert

-I have applied a patch (#6682) and done the basic testing on my existing testing site.
-Tested On Joomla 3.4.1

-I found something, That you must check. Please refer screenshots.

@aasimali
Please open new issues, one for each of your further requests.

I used the "instruments" that come from Joomla Core. Styling is the same like in other list views.

• E.g. Clear button for Search only. It's easy to add one in a /layouts/ override inside the /html/ folder of the template (or in a custom component) for all list views in backend if you want it.

But it should be discussed separately if this is wanted globally in CoreCode in the future.

• E.g. "Looks weird for long terms". would be a global LESS/CSS change that was not part of my PR. It's normal bahaviour to have fixed widths for the bootstrapped select/chosen boxes. I've tried lots of (bad) solutions in my custom components. Results are more weird than status quo ;-)

Should also be discussed separately if this is wanted globally in CoreCode.

On the other hand you can easily implement custom CSS by creating e.g.
/administrator/templates/isis/css/custom.css
and change styling of HTML elements like you need it.

• "Rename the buttons". You can create your own labeling via Extensions > Languages > Overrides. Or open a new issue.

I would be happy if you would confirm my PR at page #6682 as "tested successfully" if no other issues concerning functionality occured. Thank you.

@bertmert

I confirmed that, your PR ( #6682) working as expected.

One thing, I would like to share with you is, I am not a technical guy, I can not override anything and whatever suggestion/Bug I give/report to Joomla, They are purely at Global level

However, I will open a new issues for the above reported issues Once I get time.

Thank you.

Closing as the PR has been merged

@aasimali Please reopen your issue here!
(My PR has been removed and I will not start a rework as long template Hathor needs a different and obscure handling.)

See and test new PR. Also for this issue here.
#6958

Thanks @bertmert i'm closing in favor of your PR
