angular - Ionic 2 linked select option -


in ionic 2 how can create linked select option.

for example:

<select>     <option selected hidden>select country</option>     <option>germany</option>     <option>belgium</option> </select> <select>     <option selected hidden>select city</option>     <option>berlin</option>     <option>dortmund</option>     <option>hamburg</option>     <option>brussels</option> </select>

and when select germany in select option 2 shows german cities , when choose city display data city

i suggest dynamically populating second select options. have object of countries index list of related cities , attach event listener change event on county select populates cities select options:

{     germany: ['berlin', 'dortmund', 'hamburg', 'brussels', ...]     belgium: [...],     england: [...], }

then populate county list using indexes of object , have entire thing dynamic.
