Hi,

Can you show me the full code of your application?

Describe, please, what do you want to achieve by using getValueOfSelectCountry method.

If you want to get the value of selected option it's enough to use your getValueOfSelectCountry like this:

  <MDBSelect
        ....
         getTextContent={this.getValueOfSelectCountry}
        ...
  />

    getValueOfSelectCountry = value => {
        console.log(value)
   }

If you want to change the state of your options using other methods you can try this example :

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

class App extends Component {
  state = {
    allCountries: [
      {
        text: "Germany",
        value: "2",
        checked: true
      },
      {
        text: "France",
        value: "3",
        checked: true
      },
      {
        text: "Poland",
        value: "4",
        checked: true
      },
      {
        text: "USA",
        value: "1",
        checked: true
      },
      {
        text: "Japan",
        value: "5",
        checked: true
      }
    ]
  };

  transformCountries = () => {
    let allCountries = [...this.state.allCountries];
    allCountries = allCountries.map(country => country.checked === true ? country.checked === false : null)

    this.setState({ allCountries })
  }

  render() {
    return (
      <div>
        <MDBSelect
          selectAll
          search
          multiple
          color="primary"
          options={this.state.allCountries}
          selected="Choose your option"
          label="Country"
        />

        <MDBBtn onClick={this.transformCountries}>Click</MDBBtn>
      </div>
    );
  }
}

export default App;

In the example above I found Countries with checked===true and then set checked to false by clicking on the button. You can follow the logic of the transformCountries method and change your option's state whatever you want.

Hope I could help.

HI,

I have a similar problem i would appreciate your help with this

here in this.state.valueofCountry.temp i am maintaining the options:

    <MDBSelect
         selectAll
         search
         multiple
         color="primary"
         options={this.state.valueofCountry.temp}
         getTextContent={this.getValueOfSelectCountry}
         selected="Choose your option"
         label="Country"
      />
this.state.valueofCountry.temp=allCountries: [

  {
    text: "Germany",
    value: "2",
    checked: true,
  },
  {
    text: "France",
    value: "3",
    checked: true,
  },
  {
    text: "Poland",
    value: "4",
    checked: true,
  },
  {
    text: "USA",
    value: "1",
    checked: true,
  },
  {
    text: "Japan",
    value: "5",
    checked: true,
  }
],

    getValueOfSelectCountry = value => { 
    let countrySelectionOptions = this.state.valueofCountry.temp;     
    countrySelectionOptions.forEach(function (country) { 
    var r = /country.text/ if 
         (r.test(value)) { country.checked = true } });

    let found_any = find(countrySelectionOptions, { checked: true });
    if (!found_any) {
        value = ''
    }
    this.setState({ ...this.state, valueofCountry: { value: value, temp: countrySelectionOptions } }, function () {
        console.log(this.state);
    });
};

The problem is the selected value doesnt show properly in the select box, here is a screen grab please advice
