/**
* Represents a select menu in a message.
*
This is an interactive component and usually located within an {@link net.dv8tion.jda.api.interactions.components.ActionRow ActionRow}.
* One select menu fills up an entire action row by itself. You cannot have an action row with other components if a select menu is present in the same row.
*
* The selections a user makes are only visible within their current client session.
* Other users cannot see the choices selected, and they will disappear when the client restarts or the message is reloaded.
*
*
Examples
*
{@code
* public void onSlashCommandInteraction(SlashCommandInteractionEvent event) {
* if (!event.getName().equals("class")) return;
*
* StringSelectMenu menu = StringSelectMenu.create("menu:class")
* .setPlaceholder("Choose your class") // shows the placeholder indicating what this menu is for
* .setRequiredRange(1, 1) // exactly one must be selected
* .addOption("Arcane Mage", "mage-arcane")
* .addOption("Fire Mage", "mage-fire")
* .addOption("Frost Mage", "mage-frost")
* .setDefaultValues("mage-fire") // default to fire mage
* .build();
*
* event.reply("Please pick your class below")
