Drupal 8.x

Hi,

I'm building a Website where editors add places and descriptions to locations. It would be awesome, if they could add polylines / Routes for the Users. Are there any modules like leaflet or gmap where users/editors can add polylines? 

Sry for my englisch.

Hello,

I wanted to know if it exits a way to exchange line and column of a table. By default, informations display in columns but I don't like it.

Any idea ?

Thank you

Ok.. this must be something simple that I'm not seeing. 

I've used views to create a CSV file of a content type from a D7 site. post format looks like it's this: Y-m-d h:i:s O

I'm trying to import it into a test D8 site. The field currently giving me trouble is the post date field, generating this error: 

• The content Lorem Ipsum failed to validate with the following errors:
  • created.0.value: This value should be of the correct primitive type.

  Please check your mappings.

Hi,

I'm coding a custom module with view relationship support to custom table.

I have succesful added the relationship via the hook_field_views_data in moduleName.view.inc

[basetheme = Bartik]

I am building a website with Bartik as my basetheme; that is, that in my THEME.info.yaml file, I have chosen Bartik as my basetheme.  I am trying to resize one of the container windows on the front page.  Opening up Chrome Developer Tools, I find that the height property is greyed out on that container window and the same is true for all contained interior <divs>.  My guess is that the height property must be being set by javascript and not css.
