1 Introduction

Input Elements are widgets in the Web Modeler that are typically used to allow end-users enter or edit data.

Input Elements can only function inside a data container (a list view or a data view). You can either place widget in an existing data container; or click Wrap with a new data view in Properties to create a data view automatically and place an input element inside it.

2 Input Elements Overview

You can find the description of input elements available in the Web Modeler in the table below:

Input Element Description
Text Box A text box is used to allow end-users to enter, edit, and display a text. For example, end-users will be able to enter their names.
Text Area A text area is used to enter, edit, and display a long text that can take several lines, for example, the description of a product.
Date Picker A date picker is used to allow end-users select a date in a calendar, for example, when selecting a day for a delivery.
Drop Down A drop-down widget is used to allow end-users pick an option from the preset list of options. For example, users can select a color of a product.
Reference Selector A reference selector is used to select and display associations. To use the reference selector you need a many-to-one association in the domain model. For more information, see Association Properties in the Web Modeler. For example, if a customer has several addresses, the user can select a delivery address from them. In this example, several addresses can be associated with one customer (many-to-one association).
The reference selector is displayed as a drop-down.
Check Box A check box widget is used to allow users to mark a value as true or false. For example, users can tick a box to sign up for the newsletter.
Radio Buttons Radio buttons are used to allow users select the option from a number of preset ones. For example, users can select from several possible locations for picking an order up.

3 Properties

3.2 General Section

The General section has common properties for every input element, but may also contain specific ones.

3.2.1 Common Properties

Common properties of input elements are described in the table below:

Property Description
Show Label Enable this property if you want to show a label (name) of a widget to the end-user.
This property is enabled by default.
Label This property only appears if Show Label is enabled. Specify the name that will be displayed to the end-users. When you select an attribute, the name of the attribute is filled out as a label.
Editability Editability indicates whether the end-user will be able to change the value displayed by the widget. Possible values are the following:
  • Editable – the value displayed by the widget is editable
  • Read-only – the value is in read-only mode

Input Element Property Description
Text Area Grow Automatically When enabled, the text area grows automatically depending on the amount if text filled out in it.
This property is disabled by default.
