DropdownList

iOS
Android

Description

The DropDownList creates a vertical drop-down list box. Single or multiple items can be selected from a DropDownList. Drop-down lists can be flat or nested. When you create nested drop-down lists, only the parent list and the current list are visible at the same time. Drop-down lists that overflow are automatically styled to show that there are more selections.

Example

import React from "react";
import { View, DropdownList, DropdownListItem, LinearLayout, Text, Scene, Prism } from "magic-script-components";

export default class MyApp extends React.Component {
  constructor(props) {
    super(props);

    this.stateList = [
      "New",
      "In Progress",
      "On Hold",
      "Resolved",
      "Closed",
      "Canceled"
    ];

    this.state = { selectedState: "Select" };
  }

  onSelectedStateChanged = event => {
    if (event.SelectedItems.length > 0) {
      const item = event.SelectedItems[0];
      this.setState({ selectedState: item.label });
    }
  };

  render() {
    const { selectedState } = this.state;

    return (
      <Scene>
        <Prism size={[1, 1, 0.2]} >
          <View name="main-view" localPosition={this.props.localPosition} >
            <LinearLayout
              alignment={'center-center'}
              defaultItemAlignment={'center-center'}
              defaultItemPadding={[0.03, 0.03, 0.03, 0.03]}
              orientation={'horizontal'}
            >
              <Text textSize={0.03}>State:</Text>
              <DropdownList
                textSize={0.03}
                text={selectedState}
                onSelectionChanged={this.onSelectedStateChanged}
              >
                {this.stateList.map((item, index) => (
                  <DropdownListItem key={item} id={index} label={item} />
                ))}
              </DropdownList>
            </LinearLayout>
          </View>
        </Prism>
      </Scene>
    );
  }
}

Name	Type	Default Value	Required	Description
text	string	n/a	N	The UTF-8 encoded text to initially set the drop-down list label to.

Element Properties

Name	Type	Default Value	Description
iconSize	number	n/a	Sets the button icon size in scene units.
iconColor	vec4	n/a	Sets the RGBA color of the button icon.
listMaxHeight	number	`0`	Sets the maximum height of a drop-down list. The default value (`0`) indicates there is no limit and the list grows as long as it needs to. Setting a value greater than zero will set the maximum height such that if a list is larger than the maxiumum height, the list content scrolls.
listTextSize	number	0.025	Sets the size of the list text. If no size set, the list uses the same text size used in the drop-down list menu button itself. If no text is present on the menu button, the default text size is used.
maxCharacterLimit	number	n/a	Sets the maximum amount of characters to be used per list item label before adding '...'. The default character limit is `0`, which means there is no limit and the labels scale to the largest item.
multiSelect	boolean	false	Sets the multi-select mode of the drop-down list.
showList	boolean	false	Shows the drop-down list or not.
selected	object	n/a	Sets the selected state of a `DropDownListItem`. This uses the ID set for a particular `DropDownListItem`, which should be unique. If the ID is not unique, the first item with that ID is set. State are updated upon closing and reopening the list when the list is visible.
