+A lenyíló lista tulajdonképpen egy szövegmező és egy lista kereszezéséből jött létre.
+Ezért a tulajdonságai és eseményei is többnyire ettől a két vezérlőtől öröklődnek.
+A lenyíló listából csak egy elemet lehet kiválasztani és csak egyoszlopos megjelenítésre alkalmas.
+Ha a lista elemeinek száma több mint az egyszerre megjeleníthető sorok száma, akkor a görgetősáv autómatikusan megjelenik.
+Azt hogy a lenyíló lista milyen stílusú legyen, a DropDownStyle tulajdonság határozza meg.
