I use select-field from material-ui framework of latest 0.15.4 version with react of version 15.4.0. I try to add blank menu-item to select-field to be able to diselect value for 'dropdown' field when I click on it. When I try to add it in the way like
<MenuItem value="" primaryText="" />
it doesn't appear in the dropdown list of items. What is the proper way to add functionality of selection blank field in SelectField?

Reset to default 5setting the MenuItem value to "" and primaryText to "" will make it invisible in the choices.
I suggest you do this:
<SelectField value={this.state.some_key}>
<MenuItem value="Choice1" primaryText="Choice1" />
<MenuItem value="Select" primaryText="Select" />
</SelectField>
and then on onChange:
onChange = (event, index, value) => {
if(value === "Select") {
this.setState({some_key = ""})
}
}
This will show blank input on the field once the "Select" is clicked.
