The Multi-Currency feature is a function that converts the original price into a new value based on the currency a user has selected from the Multi-Currency Widget.
The theme has 1 main currency and 1 price per property only. There is no option to have different prices for each property (like price in Euro and price in USD).
Each price will be originally displayed using the main currency you set in Theme Options -> Price & Currency

To manage the multi currency options navigate to Theme Options > General > Price & Currency.

Here you have the following options:

  1. Price number thousand separator (for properties price)
  2. Price symbol (for property price)
  3. Price label (for multi currency widget)
  4. Price symbol position. Options are before/after price value.
  5. Enable or disable API for multi-currency and set multi-currency options.

How to set Multi Currency Widget

If you want to use the multi-currency feature, first add a default currency in the admin options.

Add the new currency you can also add currency value.

This value will be used to transform the price from the main currency in this new currency.

For ex 1 EUR = 0.73 x 1 GBR . (0.73 is the GBR).

Auto-exchange currency convertor

For the currency value to change automatically you must set all these 3 settings correctly:

  1. You must enable Enable auto loading of exchange rates from (1 time per day)? AND add your Api Key
  2. Get the free api key from here and add it in Theme Options
  3. Set the Currency Code and Label according to Internation Standards
Also, since the currencies values can vary from day to day, we create a cron job that runs 1 time per day and takes the financial data from Currencyconverterapi to auto-fill these value forms in Theme Options.

Add the Widget to widget area

For multi-currency we use a widget with dropdowns – When a user changes the currency from the dropdown widget, we read the currency value you just set and convert the original price.
