props/options

data

Actual data you want to show, this is an array of either object, strings or numbers. Array or array won't work

<ComboSelect data={standardArray}/>

text

Text will be displayed as somehintg you have selected or set as a start value, default for this is "-Select me-"

let standardArray = ["JA007D", "JA008D", "JA009D", "JA010D"];

<ComboSelect text="-Select me-" data={standardArray}/>

let arrayWithObjects = [
            {text: "air-JA007D", win: "win-JA007D", value: "JA007D"},
            {text: "air-JA008D", win: "win-JA008D", value: "JA008D"},
            {text: "air-JA009D", win: "win-JA009D", value: "JA009D"},
            {text: "air-JA107D", win: "win-JA107D", value: "JA010D"}
        ];

<ComboSelect data={arrayWithObjects}/>

type

Select or multiselect, self explanatory

let standardArray = ["JA007D", "JA008D", "JA009D", "JA010D", "JA219J", "JA302J", "JA306J", "JA308J", "JA309J", "JA311J", "JA313J", "JA314J", "JA316J", "JA318J", "JA319J", "JA322J", "JA324J", "JA325J", "JA326J"];

// Pick one
<ComboSelect data={standardArray} type="select"/>

// Or just
<ComboSelect data={standardArray}/>

// Pick multiple
<ComboSelect data={standardArray} type="multiselect"/>

onChange

Returns function, which will return value that you have picked. It can work with returning just values you have selected, or whole objects if can you need to pass them around

fakeFunction(value, text) {
    console.log(value, text);
}

let standardArray = ["JA007D", "JA008D", "JA009D", "JA010D"];

<ComboSelect text="-Select me-" type="multiselect" data={standardArray} onChange={this.fakeFunction}/>

onToggle

Function that emit event for opening and closing menu. Returns boolean, true for open, false for close and value which is all selected values

fakeToggle(open, value, text) {
    console.log(open, value, text);
}

let standardArray = ["JA007D", "JA008D", "JA009D", "JA010D"];

<ComboSelect text="-Select me-" type="multiselect" data={standardArray} onToggle={this.fakeFunction}/>

search

Search through data, will show only data that contain string from search bar. On, off (default), smart (search will be shown only if there is more items then can be shown in window)

let standardArray = ["JA007D", "JA008D", "JA009D", "JA010D", "JA219J", "JA302J", "JA306J", "JA308J", "JA309J", "JA311J", "JA313J", "JA314J", "JA316J", "JA318J", "JA319J", "JA322J", "JA324J", "JA325J", "JA326J"];

<ComboSelect type="select" data={standardArray} search="smart"}/>

map

If you want to display data from objects, use map! You need to define object with key objects text and value. Text will be the one you display as a text, and value is returning in a onChange function as a paramater. If you want to return whole object, put value=true (boolean). Default is map={text: 'text', value: 'value'}, which means you will have collection of objects, and on select value will be returned and text will be shown in select.

let arrayWithObjects = [
            {text: "air-JA007D", win: "win-JA007D", value: "JA007D"},
            {text: "air-JA008D", win: "win-JA008D", value: "JA008D"},
            {text: "air-JA009D", win: "win-JA009D", value: "JA009D"},
            {text: "air-JA107D", win: "win-JA107D", value: "JA010D"}
        ];

// Key object
fakeFunction(value, text) {
    console.log(value, text) // this will display key object win and key object with text will be shown in tn select.
}

<ComboSelect data={arrayWithObjects} map={text: 'text', value: 'win'} onChange={this.fakeFunction}/>

// Whole object
fakeFunctionObject(value, text) {
    console.log(value, text) // this will display {text: "air-JA007D", win: "win-JA007D", value: "JA007D"} and key object with text will be shown in tn select.
}

<ComboSelect data={arrayWithObjects} map={text: 'text', value: true} onChange={this.fakeFunctionObject}/>


// Map through function, you allways get item, and have to return value
selectText: function(item){
    return item.hereIs.objectFor.text
}

// function
fakeFunctionObject(value, text) {
    console.log(value, text) // this will display {text: "air-JA007D", win: "win-JA007D", value: "JA007D"} and key object with text will be shown in tn select.
}

<ComboSelect data={arrayWithObjects} map={text: this.selectText, value: true} onChange={this.fakeFunctionObject}/>

sort

You can sort data, numbers, alphanumercial (alphanum) or don't sort at all. By the default, it will sort strings, but only if the parameters in value are strings

// Proper sorting 
let nummericArray = [3, 1, 11, 111, 21, 32, 14, 32, 442];
<ComboSelect text="-Select me-" type="multiselect" data={nummericArray} sort="number"/>
let standardArray = ["DDD", "CCC", "BBB", "AAA"];
<ComboSelect text="-Select me-" type="multiselect" data={standardArray} sort="string"/>
let standardArray = ["win-JA007D", "win-JA0008D", "win-JA009D"];
<ComboSelect text="-Select me-" type="multiselect" data={standardArray} sort="alphanum"/>

Active and inactive icons

Can be default, custom or off. For custom just put class that you want, and it would be assigned to icon class. For default, just leave as is. And for off use false or 'off'

let standardArray = ["JA007D", "JA008D", "JA009D", "JA010D"];

<ComboSelect type="multiselect" data={this.state.data} value={this.state.data[1]} iconSelectInactive={false} iconSelectActive={false}/>
<ComboSelect type="multiselect" data={this.state.data} value={this.state.data[1]} iconSelectInactive={'fa fa-check-circle'} iconSelectActive={'fa fa-check-circle'}/>
<ComboSelect type="multiselect" data={this.state.data} value={this.state.data[1]}/>

disabled

Self explanatory

let standardArray = ["JA007D", "JA008D", "JA009D", "JA010D"];

<ComboSelect type="multiselect" data={this.state.data} value={this.state.data[1]} disabled}/>

scrollHeight, scrollMaxHeight and prefferedDirection

scrollHeight lets you choose height of the scrollable options area. Similarily, scrollMaxHeight will set max-height. Both of those props require preferredDirection prop, which allows you to choose the direction of the options area.

const heightProps = {
    scrollHeight: 200, // number
    preferredDirection: 'down' // 'top' | 'down'
};

const maxHeightProps = {
    scrollMaxHeight: 100, // number
    preferredDirection: 'top' // 'top' | 'down'
};

<ComboSelect type="multiselect" data={this.state.data} value={this.state.data[1]} {...heightProps} />

<ComboSelect type="select" data={this.state.data} value={this.state.data[1]} {...maxHeightProps} />
