TypoScript for creating a language dropdown menu (with select and option tags)

constants.ts

global {
    languageLabels {
		current = Deutsch
		availableSysLanguageUids = 0,1
		additionalParams = &L=0 || &L=1
		availableLabels = Deutsch || English
	}
}

navigation.ts

lib.navigations.language = HMENU
lib.navigations.language {
	special = language
	special.value = {$global.languageLabels.availableSysLanguageUids}

	1 = TMENU
	1 {
		NO = 1
		NO {
			doNotLinkIt = 1

			stdWrap.cObject = COA
			stdWrap.cObject {
				5 = LOAD_REGISTER
				5 {
					languageLink.cObject = TEXT
					languageLink.cObject.typolink {
						parameter.data = page:uid
						additionalParams = {$global.languageLabels.additionalParams}
						returnLast = url
					}
				}

				10 = TEXT
				10 {
					value = {$global.languageLabels.availableLabels}
					dataWrap = <option value="{REGISTER:languageLink}">|</option>
				}
			}
		}
		ACT < .NO
		ACT.stdWrap.cObject.10.dataWrap = <option selected="selected" value="{REGISTER:languageLink}">|</option>
		USERDEF2 < .ACT
	}

	wrap = <select class="languageSelect">|</select>
}

Thanks for sharing!

Very nice work. Maybe Line 36 could be:
wrap = <select class="languageSelect" onchange="window.location = this.options[this.selectedIndex].value">|</select>
This will redirect the user after language selection.

Thanks for sharing, it was very useful for me today!
