)

type myForm struct {
    Colors []string `form:"colors[]"`
}

func main() {
    r := gin.Default()

    r.LoadHTMLGlob("views/*")
    r.GET("/", indexHandler)
    r.POST("/", formHandler)

    r.Run(":8080")
}

func indexHandler(c *gin.Context) {
    c.HTML(200, "form.html", nil)
}

func formHandler(c *gin.Context) {
    var fakeForm myForm
    c.Bind(&fakeForm)
    c.JSON(200, gin.H{"color": fakeForm.Colors})
