Drupal 8.x

I am using Heading module https://www.drupal.org/project/heading it basically two fields widget one is text box(drupal core textbox) where user can type the text and second is dropdown where user can select the heading type.

now issue is that drupal core text box having limit 128 characters i want to increase the size. i already have the data in this field kindly guide me how can i do that

So there is this good module :https://www.drupal.org/project/webform, which let me create forms, i want to save these forms in my site , and i want a search engine api ( a module maybe?) that is related only to these forms, so if i search something related to forms, it should show all forms related to it, for example in form i have ``company name`` and let say the company name is :drupal, when you search drupal in the search engine, it should show all forms that has drupal as the company name.

I am new to Drupal and having some issues with the cogwheel button on all of content types when I want to manage their display. When I click the gear / cogwheel icon "please wait" message shows up for a second then then nothing happens, no options to change. I saw this log below (there is no Drupal log).

I tried it with both enabling / disabling JS Agreggation under Configuration > Development, no success!

Hello

I have just informed that the major newspaper and magazine national websites in Greece are made from Drupal! For example https://www.ethnos.gr/ or https://www.sdna.gr/. 

I have just start learning Drupal while im building websites with wordpress

I want to ask just a question. How can i freely design my regions on a web site in drupal where i would place my blocks like the websites i mentioned above? 

I have, say, 3 content types, I want to create a single page, node or view that holds the nodes from this content types.

So I have node A with 4 fields, B with 2 fields and C with 5 fields (A, B, C are of different content types) and I want to crerate a collection of this nodes on a single page such that we have the following:

===page start====

A title
A field_1
A field_2
A field_3
A field_4

<hr>
line break or page break

After upgrading to 8.9.5 last week I noticed a problem on my shared hosting site where I was intermittently locked out of admin.
