Setting Default Values on Select Menus.

This tutorial will cover how to set the default value for a select menu (that isn't a text select menu)!

Note

This only works for the following types of select menus: user, role, mentionable, and channel. The default type of a select menu (as shown in this page) does not work for this, as that supports a "placeholder".

#include <dpp/dpp.h>
#include <dpp/unicode_emoji.h>
    
int main() {
    dpp::cluster bot("token");
    
    bot.on_log(dpp::utility::cout_logger());
    
    /* The event is fired when someone issues your commands */
    bot.on_slashcommand([&bot](const dpp::slashcommand_t& event) {
        /* Check which command they ran */
        if (event.command.get_command_name() == "select") {
            /* Create a message */
            dpp::message msg(event.command.channel_id, "This text has a select menu!");
 
            /* Add an action row, and a select menu within the action row. 
             *
             * Your default values are limited to max_values,
             * meaning you can't add more default values than the allowed max values.
             */
            msg.add_component(
                dpp::component().add_component(
                    dpp::component()
                        .set_type(dpp::cot_role_selectmenu)
                        .set_min_values(2)
                        .set_max_values(2)
                        .add_default_value(dpp::snowflake{667756886443163648}, dpp::cdt_role)
                        .set_id("myselectid")
                )
            );
        
            /* Reply to the user with our message. */
            event.reply(msg);
        }
    });
    
    bot.on_ready([&bot](const dpp::ready_t& event) {
        if (dpp::run_once<struct register_bot_commands>()) {
            /* Create and register a command when the bot is ready */
            bot.global_command_create(dpp::slashcommand("select", "Select something at random!", bot.me.id));
        }
    });
    
    bot.start(dpp::st_wait);
    
    return 0;
}

If all went well, you should have something like this!
