Select¶

Description¶

The Select component is a dropdown menu that allows users to choose one option from a predefined list.

It's a versatile tool for collecting user input in situations where there are multiple, but not limitless, choices.

Use Case¶

Filtering and Selection
- Product Catalog
- Search Results
- Event Calendar
Dynamically Changing Options
- Dependent Dropdowns
- Conditional Options
- Personalized Offer
Data Collection and Analytics
- Survey Questions
- Feedback Forms
- Market Research
Interactive and Engaging Designs
- Customizable Options

Interactivity¶

Search functionality: Integrate a search bar within the dropdown menu for quickly finding specific options in long lists.
Dependent dropdowns: Link multiple select components, making the options in the second dropdown dependent on the selection in the first.
Conditional options: Based on user input in other form fields, dynamically hide or show irrelevant options in the select list.
Preview features: When users hover over an option, display a preview of what happens if they select it.

Events¶

Name	Description
`onChange (element)`	The onChange event occurs when the value of a field is changed
`onFocus (element)`	The onfocus event occurs when a field gets focus
`onBlur (element)`	The onblur event occurs when a field loses focus

Methods¶

Name	Description	Parameters
`this.addClassName`	Add style class to a form item	`(fields: String`\|`String[], className: String)`
`this.removeClassName`	Remove style class from a form item	`(fields: String`\|`String[], className: String)`
`this.getComponent`	Returns a component whose id has been passed as a parameter	`(component_ID: String) : Object`
`this.getValues`	Gets the current values of all fields	`() : Object`
`this.hide`	Hides the field	`(fields: String`\|`String[])`
`this.show`	Displays the field	`(fields: String`\|`String[])`
`this.disable`	Disable select field from user interaction	`(fields: String`\|`String[])`
`this.enable`	Enable select field from user interaction	`(fields: String`\|`String[])`
`this.getValue`	Get A Value From a component	`(fieldName: String)`
`this.setData`	Set the data in the field. The Value object should be of type { componentId: componentValue }	`(Value: Object)`
`this.refreshFieldDataSource`	Refresh the datasource data bound to the whole page

Info

The show() and hide() methods can also be used to control the visibility of a select component in response to user input.
Fields refers to a component ID or a list of component IDs. You can fetch the ID from the Component Attribute panel in the Page Builder.
Before using this.show(fields), make sure the component is hidden. This can be done using this.hide(fields) or by enabling the Hidden checkbox in the Component Attribute panel.
Before using this.enable(fields), make sure the component is disabled. This can be done using this.disable(fields) or by enabling the Disabled checkbox in the Component Attribute panel.

Steps to use the methods for the Page Builder components¶

Go to Form Attribute Action Panel Setting (Mounted | refresh | click 'Add action').
Write the method/code as shown in the Example below.
Click on Save.
On the main screen click on Save again.
Click on Preview to see the code in action.

Example

this.addClassName(fields, className)
- Go to Form Attribute Style Sheets add the class
```
.abc{ // abc is the class name
background-color: red;
}
```
- Follow the steps mentioned above, under Steps to use the methods for the Page Builder components
- this.addClassName('select_rzaltclo', 'abc')

this.removeClassName(fields, className)

this.removeClassName('select_rzaltclo', 'abc')

this.getValues()

var data = this.getValues();
console.log(data);

this.hide(fields)

var fields= ['select_rzaltclo']
this.hide(fields)

this.show(fields)

var fields= ['select_rzaltclo']
this.show(fields)

this.disable(['fields'])
```
this.disable(['select_rzaltclo'])
```
this.enable(['fields'])
```
this.enable(['select_rzaltclo'])
```

this.getValue('fieldName')

var selectname = this.getValue('select_rzaltclo');
console.log('getValue', selectname);

this.getComponent('component_ID')

var selectname = this.getComponent('select_rzaltclo');
console.log('getComponent', selectname);

this.setData(Value)

this.setData(
 {"select_rzaltclo": "Option 2",});

this.refreshFieldDataSource(datasource)

const dataSource = 'Name Of The Data Source Function'
this.refreshFieldDataSource(dataSource)

Config¶

Name	Description	Icon
ID	The select component's unique identifier
Name	[Optional] The display name of the select field
Width	[Optional] Width of the field
Label Width	Width of the label associated with an input field. It determines the horizontal space occupied by the label text
Label Wrap	If the label is longer than the allowed width the text will continue on another line

Text Prompt	A description to aid the user when completing the field
Multiple	Choose multiple options from the available list
Searchable	Enable this option to search the options from the list
Option	Choose either Static or Dynamic way of adding data to the options of the Select Static data refers to a fixed set of options that are pre-defined and loaded into the select at the time of initialization Dynamic data are options fetched as needed from sources like databases or APIs. The select updates choices based on user selections. You select from Data source which refers to the origin of the data; Function which refers to the code that manipulates the data, and Assigned Value which refers to the specific value stored or associated with a data element
Custom Class	An HTML class attribute which allows further customisation See Form Attribute > Style Sheets
Attribute Action	Enable Data Binding to connect the data to UI. Enable Hidden action to hide the field. Enable Disabled action to make the field unusable. Enable Show Clear button action to make the clear button visible.

Validation¶

Form validation is the process of checking the data entered into a form to ensure that it's valid and complete.

This helps to prevent users from submitting forms with invalid data, which can cause problems for the application that's processing the form.

Form validation can be performed using a variety of methods, including:

Name	Description
Required	If enabled, then the field value can't be empty, otherwise an error message is emitted
Custom Validation Rules	(rule, value, callback) => {
	rule: Verification rule, you can view the verification configuration information through this parameter; rule.field can get the field identifier of the current verification
	value: Value of the current field
	callback: Callback function (must be called) upon completion of validation; callback('Error message')/ callback(new Error('Error message')). These are two ways to return an error message

Info

The callback() function is also called to verify success in the custom validation method.
