keyboardShouldPersistTaps |
never/always/handle |
never |
Determines when the keyboard should stay visible after a tap. If never, tapping outside of the focused text input when the keyboard is up dismisses the keyboard. When this happens, children won't receive the tap. If always, the keyboard will not dismiss automatically, and the scroll view will not catch taps, but children of the scroll view can catch taps. If handled, the keyboard will not dismiss automatically when the tap was handled by a children, (or captured by an ancestor). |
autoFocus |
Boolean |
false |
If true, focuses the input on componentDidMount(). |
In addition, the following styling props (each of which must be an Object consisting of styles) can be passed in:

By default the filter input field allows you to filter by the option label
that's displayed on the screen.
But you can also attach a searchKey attribute to
each option for the filtering algorithm to use. For example, we can allow the
user to filter by continent as
well as country name, even though we don't display the continent name:
render() {
const { visible } = this.state;
const options = [
{
key: 'kenya',
label: 'Kenya',
searchKey: 'Africa',
},
{
key: 'uganda',
label: 'Uganda',
searchKey: 'Africa',
},
{
key: 'libya',
label: 'Libya',
searchKey: 'Africa',
},
{
key: 'japan',
label: 'Japan',
searchKey: 'Asia',
},
{
key: 'estonia',
label: 'Estonia',
searchKey: 'Europe',
},
];
return (
<View style={styles.container}>
<ModalFilterPicker
onSelect={this.onSelect}
onCancel={this.onCancel}
options={options}
/>
</View>
);
}If you run the above example, you will be able to type africa into the filter
input field to see all the countries within Africa.
