A module where you first have to think about the usefulness of it ... It converts text fields (also title field) to an image (in png). You can set background and letter color. With the module there are also a number of fonts, but you can add them yourself. All text, becomes an image.
There is something like 'field validation', which determines what is allowed to be typed in a field and what is not. However, the title field is a special case. It is not regarded as an ordinary field. This module makes it possible to set a validation for the title field as well.
By default, the title of a node is offered as a block. Usually this block is placed at the top of the content. This module allows you to place the title as a field between all other fields and to give some layout.
This module is just the opposite as Blockfield. It converts a field into a block. For example, you can show an image of a content type somewhere in a block instead of between the other fields. This can be useful and is actually a kind of 'light' Panels or Display Suite.
A module that allows you to choose a color. You wonder what this can serve for? Well ... I combine it with the Token module and I let someone determine the background color of the site without the person needing Drupal knowledge.
If you use a star rating field than you have to fill in the number (1-10). This number turns into a symbol in the display mode. This module makes it possible to use the same symbols for the input also.
Simple module that allows you to override the field label in the display of the field. I usually give a field a name with the content type in it. (eg immo_image) Easy to use in views. With this module one can override this technical name.
An image of the SVG (Scalable Vector Graphics) type can not be used in Drupal. Not even by adding the filetype in an imagefield setting. Illustrator and Coreldraw use SVG formats. It has some advantages (sharp, less memoryspace,...)
This module allows you to use pictures in the CKEditor text fields that popup by clicking. It is not a gallery.. One image at the time.. It is usefull when you put small pictures in the text. Visitors can look at them in full size by clicking.
You want a default textfield every time the node shows? This module does the job. Set the input not visible if needed. You can put the field wherever you want, just like another field. I used is as a replacement for a field label.
If you use the teephone module, than this is a handy one...It checks the number of digits in the context of the country code. It validates the amount of numbers. It does not check whether the number exists or not!
This module competes with the Bricks module for Bootstrap. A little bit less flexible, but more settings for the layout. It works with Bootstrap 4 themes like Breeze. This theme adds some nice CSS to the module.
Display suite (short DS) is very popular. It offers you the possibility to split up your content block into regions (= extra blocks). Within these regions you can put your fields en add some CSS. DS allows you to make view modes for content types, others than teaser and full mode.
After the installation of the field collection module, you can make subfields in a field. Imagine you have a field with the name of a exposition and a field of their dates. These fields belong always together.
