Expected behavior

Select All option should be enabled by default for multiselect component

Actual behavior

Not able to view Show All option in the multiselect component and padding to the left and right sides is zero

Resources (screenshots, code snippets etc.)

import React, { Component } from "react";
import { MDBSelect } from "mdbreact";

class SelectPage extends Component {
  state = {
    options: [
      {
        text: "Option nr 1",
        value: "1"
      },
      {
        text: "Option nr 2"
        value: "2"
      },
      {
        checked: true,
        text: "Option nr 3",
        value: "3"
      },
      {
        text: "Option nr 4",
        value: "4"
      },
      {
        text: "Option nr 5",
        value: "5"
      }
    ]
  };

  render() {
    return (
      <div>
        <MDBSelect
          multiple
          search
          options={this.state.options}
          selected="Choose your option"
        />
        <label>Example label</label>
      </div>
    );
  }
}

export default SelectPage;

I've used the above code snippet for multiple select with search

Please let me know for any further information

Thanks :)
