Adding Custom CSS Classes

Dynamicforms library uses Bootstrap 4 classes for styling. A custom CSS class can be defined for:

  • Form tag - By default empty. This class can be used for specific styling of each form. It can be added by defining “cssClass” property in the JSON configuration.

Example:

{
  "cssClass": "customFormClass", // This can be used to add custom styling class on the form tag
  "formGroups": [
    {
      "groupCode": "firstFormSection",
      "fieldConfigs": [
          // controls defined here...
  • Form group (section) - By default, dynamicforms library renders “row” Bootstrap class here. Defining cssClass in “formGroups” section of the JSON configuration will add class to the default class. It can be added by defining “cssClass” property in the JSON.

Example:

{
  "cssClass": "customFormClass",
  "formGroups": [
    {
      "groupCode": "firstFormSection",
      "cssClass": "customSectionClass",  // This can be used to add custom styling class to the section (Form Group),
                                         // it will be added to the existing bootstrap's "row" class,
                                         // in this case each section would have "row customSectionClass".
      "fieldConfigs": [
          // controls defined here...
  • Individual control - By default, dynamicforms library renders “col-12” Bootstrap class here, which results in one-column design. Defining a “cssClass” property in the control section of the JSON will add the default class. You can also override the default Bootstrap “col-12” class by defining a “gridClass” property in the same section of the JSON definition.

Example:

{
    "fieldConfigs": [
        {
            "type": "input",
            "name": "firstFormSection",
            "gridClass": "col-6",            // This can be used to override the default FSA (col-12) 1-column layout

            "cssClass": "customControlClass" // This can be used to add custom styling class to control,
                                             // it will be added to the existing bootstrap's "col-6" class,
                                             // so in this case each control would have "col-6 customControlClass"
            "required": true,
            "label": "How much life insurance coverage do you require?",
            "validations": [

HTML

If we consider a form with two sections and one control per section, a basic HTML structure by default would consist of:

<form class=""> // Form class, empty by default
    <div class="row"> // Form Group class, "row" by default
        <cx-input class="col-12"> // Control wrapper class, "col-12" by default  
            // Input control-1
        <cx-input>
    </div>
   <div class="row">
        <cx-input class="col-12">   
            // Input control-2
        <cx-input>
    </div>
</form>

Adding our classes from examples above would result in the following HTML:

<form class="customFormClass">  // Custom class is added.
    <div class="row customSectionClass"> // Custom class is added to default class.
        <cx-input class="col-6 customControlClass"> // Custom class is added to default class, and grid class is REPLACED
            // Input control-1
        <cx-input>
    </div>
   <div class="row">
        <cx-input class="col-6 customControlClass">   
            // Input control-2
        <cx-input>
    </div>
</form>
